Galatians 2:1; Galatians 2:9

1 Then after an interval of fourteen years I went up again to Jerusalem with Barnabas, taking Titus along also.

9 and recognizing the grace that had been given to me, James and Cephas and John, who were reputed to be pillars, gave to me and Barnabas the right hand of fellowship, so that we might go to the Gentiles and they to the circumcised.
